如何通过bash脚本检查文件是否存在? [英] How to check file exists via bash script?

问题描述

我正在尝试克隆一个仓库，并在通过bash脚本完成后对其进行测试.我已经基于 Bash Shell编写了测试代码:检查文件是否存在.

I'm trying to clone a repo and test it after is done via bash script. I have written my test code based on Bash Shell: Check File Exists or Not.

#!/bin/bash

echo "*** TRY TO INIT INFER ***"

# Clone Infer
INFER_GIT_PATH="https://github.com/facebook/infer.git"
echo "> Try to Clone Infer from ${INFER_GIT_PATH}"
git clone ${INFER_GIT_PATH}

INFER_PATH="/infer/infer/bin/infer"
[ -e ${INFER_PATH} ] && echo "Infer downloaded successfully" || echo "Something went wrong :("

尽管回购可以成功下载并且/infer/infer/bin/infer.sh存在，但我总是收到Something went wrong :(消息.

Although repo can be downloaded successfully and /infer/infer/bin/infer.sh exists, I'm always getting Something went wrong :( message.

任何建议将不胜感激.谢谢.

Any suggestion would be appreciated. Thanks.

推荐答案

将其更改为此(使用相对路径):

Change it to this (use a relative path):

INFER_PATH="./infer/infer/bin/infer"
[ -e ${INFER_PATH} ] && echo "Infer downloaded successfully" || echo "Something went wrong :("

它应该可以工作.
